SmCo Magnet: Space probe,national defense and military ,microwave appliance,communication,medical equipments,motors, instruments, various magnetism spreading devices,sensor,magnetic processor,magnetic lifter,etc.
It can be manufactured by sintering, compression bonding, injection molding, and extrusion. The sintered form holds the highest energy product of up to 51MGOe, while the bonded form holds a lower energy product of up to 10MGOe.Furthermore,The majority of NdFeB magnets are anisotropic and can only be magnetized in the orientation direction.
NdFeB Magnets are prone to corrosion in humid environments, It usually need surface treatment according to customer's requirements to protect magnet. Surface Treatment Methods are Zinc,Nickel,Chrome,Silver or Gold Plating, Phosphor,Spray Epoxy Resin etc.
Main features
